Onboard sound suddenly not working

I'm running a Core i7 920 on an Asus P6T Deluxe V2 motherboard, and have been using the onboard audio for years. Upgraded to Windows 10 about two weeks ago, and have had no issues until now. This morning my audio symbol in the system tray is showing a red X. I thought it was just muted, but when I click on the audio symbol, it starts up a troubleshooter that says I have no audio device installed. Went to Device Manager, and it doesn't even have an entry for Sound, Video and Game controllers. I downloaded the audio driver for the motherboard, but it won't install--gives me an error that the audio drivers don't support my hardware. Would appreciate any suggestions!!

I think you might be stuck until a suitable Win 10 sound driver comes along or one is shown on your driver website. To my dismay, on Win 10 MS automatically apply driver updates too. I appreciate that the sound was working earlier but Win 10 seems to be in a state of continuous updates, so it is likely that a buggy fix caused it.

Whatever, also keep watching here for other ideas.

EDIT:I'm assuming you got your drivers from your computer manufacturers website and not some third party driver outfit.

I don't think you will be able to roll back without an entry in Device Manager. Are there any errors showing or "unknown devices"?

Keep an eye out on the Asus site for Win 10 drivers - several manufacturers are not yet up to steam.

Another thought:As there is no entry I suppose it might be down to a hardware failure and nothing to do with the Win 10 upgrade and drivers. If that's the case then adding a card would be a possible way forward.
